Inverters & Converters

About this product VFD frequency converter 4 kW 220 V. Model H100-4S2-1B regulates the speed of 3-phase motors via a variably adjustable output frequency from 0 to 1000 Hz. The converter accepts 220 V as an input with 1 or 3 phases and delivers 3 phases at the output with 0 to 220 V. Input and output currents are each rated from 0 to 17 A, suitable for many motors and spindles in the 4 kW range when motor data and ramps are correctly parameterized. The input frequency of 50 or 60 Hz allows operation on common power supplies. The stepless control allows the speed to be adjusted to the tool material or flow rate, e.g., in CNC spindles, fans, pumps, or compressors. This promotes smooth operation, reduces unnecessary load peaks, and improves process control under varying loads. V/F control and vector control. The inverter offers two control modes, allowing you to configure the drive to suit your application. V/F is suitable for robust, standard tasks, while vector control can support more precise torque control under varying loads. Several modes are available for setpoint input, including digital input via the control panel, analog input, serial communication, and PID control for process-controlled speed. This allows the spindle speed to be kept stable, for example, via potentiometer, control signal, or process value. Control techniques with or without synchronization support dynamic start-up without cumbersome changes to braking parameters. This is helpful in CNC machining, mixers, winders, or conveyor systems where rapid adjustments and reproducible settings are required. Low noise and EMC optimized. Thanks to optimized PWM control, the inverter operates quietly and can reduce motor noise at variable frequencies. The overall design's EMC concept aims for low electromagnetic interference, which is particularly advantageous in CNC environments with controllers and sensors. Sufficient spacing is provided between the electronic components to allow for heat dissipation, and the housing promotes good airflow. Integrated air cooling helps maintain a stable temperature during extended operation. For reliable heat dissipation, ventilation openings should remain unobstructed, and the installation location should offer adequate air circulation. This ensures consistent performance even at higher output frequencies and under varying loads, while maintaining a pleasantly low noise level in the operating area. Multiple protection features and a robust design. The frequency converter utilizes various protection functions, including overload protection, fuse protection, overvoltage protection (above 400 V DC), undervoltage protection (below 200 V DC), restart protection, stall protection, short-circuit protection, and overheat protection. These features help protect the drive from power fluctuations, load peaks, or wiring errors, thus reducing downtime. The device is designed for operating temperatures from -5 to 40 °C, tolerates 0 to 90% relative humidity (non-condensing), and is specified for vibrations below 0.5 G. The ABS housing is flame-retardant and supports robust use in machine environments. For optimal results, grounding, cable cross-section, and motor settings should be professionally selected to ensure current and temperature remain within the specified range. Digital display and versatile application. The clear display and logically arranged keypad simplify commissioning and the adjustment of parameters such as maximum frequency, ramp time, and control mode. The detachable control panel is convenient for operation at the installation site; an extension cable is included. The inverter is suitable for spindle motors as well as CNC engraving machines, CNC milling machines, and machine tools, as well as milling and drilling machines, cutting and mixing systems, extruders, rewinders, compressors, fans, pumps, grinding machines, and conveyor systems. It can also be used as a speed controller for elevators, but is not intended for passenger elevators. With 4 kW of power and 5.5 hp, it is a suitable choice when a 220 V input is required and a 3-phase output for the motor is needed.
